'guided on the grip-stock or handle, and to novel improvements in such a Weapon, whereby especially a simplification of the same is attained and consequently the handling of the weapon, when dismounting and re-assembling the same, is facilitated. To this end, a novel fastening means for the barrel is provided, in which the barrel is held by a barrel holding device in the form of an insertible pin, after the removal of which, the barrel can be readily detached from the grip-stock or handle.

Moreover, the invention relates to the arrangement of the trigger mechanism, whose sear is not provided laterally on the maga- 1 zine box but above the same in the upper part of the grip-stock or handle and consists of a double-armed bell crank lever, Whose outwardly extending arm forms the trigger abutment pawl, whereas the trigger pawl proper is connected to the trigger itself.

Finally, an arrangement is provided for locking the breech-slide in the event of single loading and consists of a readily releasable spring locking piece or detent, which-in the event of automatic loading is overcome by the recoil, but when the breechslide is pulled by hand, it keeps the breechslide open, the said detent being however also releasable by hand by a slight pressure ,or jerk.

A recoil-loading pistol embodying the aforesaid improvements is shown in the ac companying drawings, of which,

Figures 1 and 2 are a side elevation and a front elevation respectively of the pistol, the front part of the barrel holding device being shown in section in Fig. 1; Fig. 3 is a vertical .cross-section according to line AA of Fig. 1, wherein the bayonet-joint like locking of the barrel holding device is shown; Figv 4 shows the pistol with the barrel holding device in the released position, the insertible pin formed as barrel holding device being partly drawn out; Fig.

5 is a front elevation of Fig. 4; Fig. 6 is a vertlcal cross-section according to line BB of Fig. 4; Figs. 7 and 8 are side elevation and front elevation respectively of the insertible pin; Figs. 9 and 10 show the means adapted for locking the breech-slide in the event of single loading; Fig. 11 is a side, elevation of the weapon in readiness for firing, i. e., with cocked hammer Fig. 12 is a vertical cross-section according to line C-C of Fig. 11; Fig. 13 is a longitudinal section showing the arrangement and position of the parts of the firing mechanism in the weapon in readiness for firing; Fig. 14 shows the position of the parts after firing and at the moment when the trigger pawl is separated from the sear; Fig. 15

azine, the breech-slide '2) adapted to slide on the upper part of the grip-stock provided with corresponding guides and the barrel l which is rigidly coupled with the gripstock, and partly surrounded in its lower half by the front extension 1) of the breechslide. The rear part of the breech-slide forms in the usual manner the breech bolt proper, which receives the firing pin 8 the bore being closed rearwardly by the sleeveshaped; extension a of the grip-stock 9 adapted to guidethe rear part 8' of the firing pin.

The coupling of the barrel with the gripstock is effected in the following manner: The barrel, which, as stated, is not surrounded by the front part of the breechslide, but is practically only embedded therein, hasa pin-like extension a near to its rear end, which extension, when the barrel is mounted, as shown in Fig. 4, engages in a corresponding bore in the grip-stock. Farther forward on the barrel, there is a second extension'r, which, with its lower part, bears in a groove k at the front end of the ledge is of the grip-stock and is provided with a rear milled part r and an opening 1" widened on both sides in the transverse direction. There is provided as barrel holding device an insertible pin 0 which is inserted through the opening r of the front barrel extension 1" and also with its rear ofiset part through a transverse hole 12. of the barrel extension at, whereby the latter is fixed in its bore in the grip-stock. The 5 ins'ertible pin is secured in its coupled position by a double locking arrangement, as it engages on both sides with noses p at the rear of its extension p under the shoulder is projecting from the front of the gripstock. ledge, and engages behind extension r in the recess 7* thereof with diametrically opposed cams 0 formedthereon farther toward its inner end. The insertible pin is further secured in this locking position in that the plate spring q arranged underneath the grip-stock ledge la engages with its front oifset end in the space between, the noses p. These noses are beveled, so that when coupling, 2'. e. w en the insert-ible pin with its engaging extension is rotated, the catch spring may be presseddownward and thus released from its position of rest. Only a rotation at an angle of 90 is necessary for effecting this release and also for bringing the cams 0 out of their locking position (Fig. 3) into the unlo'ckin position (Fig.

6) wherein the cams, with tir longitu inal axis, are on a level with the laterally widened opening 1" of the extension 1'. The

pin 0 may thus be drawn out at the front and-the barrel then removed from its bearing.

With regard to the arrangement of the trigger mechanism,.it comprises essentially the sear a, which, in the form of a doublearmed lever, is pivotally mounted laterally over the ma azine box m and forms with the trigger a utment lever a a single rigid piece in the form of a bell crank lever, also 40 the trigger pawl, c, which is attached directly to the trigger a and extends with itsupper beveled end 0 within the range of a corresponding beveled shoulder n of the aforesaid barrel extension n. There is provided beneath the beveled end 0 .an angular offset 0 with which, when the trigger is operated i. 6. when the trigger is pulled, the trigger pawl 0 engages around the front end of the arm a of the sear.

. The arm a of the sear a acting as trigger abutment lever is inclined upward in such a manner that it extends with its upper end into the moving path of the abutment s, so

that the firing pin 8 maybe arrested in the '55 known manner when the sear with its bell crank lever a is in the upper or arresting position caused by the plate spri b. When the trigger pawl c engages with 1ts offset a under the arm a of the sear, it lifts the same and thereby pulls the trigger abutment arm a downward,'sothat the abut- 'ment 8 is released and the cocked firing pin can advance for the purpose of firing.

When further pulling the pawl, the upper beveled end 0 slides upward on the.

'ipamvi' shoulder a? of the barrel extension. n and the pawl is turned to such an extent that its offset a is. removed from the front end of the lever arm a Thus no matter whether after firing, the trigger is still held tight, the sear w1ll return to the u per or arresting position independently of the movement of the trigger awl and under the influence of the spring 'so that when the breechslide recoils, it comes in front ofthe abutment 8 and thereby effects the. locking of the firing trolled by the spring d, which tends to keep the trigger pawl inthe normal or engaging position as shown in Fig. 13 and to return the pawl to this normal position after its upper end has been released from the pinpin. The trigger pawl a is conlike extension or shoulder, which readily takes place when releasing the trigger. I

The firing pin 8, which isguided rearwardly with its stem 8' in the sleeve-shaped end pieceg' has sleeve-shaped extensions on its plate 8 forwardly and rearwardly, the

latter extension of which receives the front endof the firing pin spring t whereas the holdin the firing pin behind the front face of the breech bolt.

A spring detent w (Figs. 10, 14s, 15 and 16) is secured by a rivet or the like against the inner wall of the grip-stock over the magazine casing and extends with its looking projection '10 into a guiding groove 9 .of the grip-stock (Fig. 15). A ledge .or strip a of the breech slide slides in this groove 9 and has a recess to (Fig. 9) on the inside, in which the projection to can enter under the influence of the elasticity of the spring detent to when the breech slide is in its rearward position (Fig. 16).

The elasticity of the spring detentw is so proportioned that the slide 12 is held retracted when opened by hand against the pressure of the locking spring The slide can be readily released from the detent byslightly pushing upon the .rearend of. the

ertia and to enter with its projection 'w into grip stock having a bore into which said extension passes, and a barrel-holding device secured to the rip stock. w
